To all whom it may concern:

Be it known that I, WALTER P. Aonnss, a citizen of the United'States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Metal Connectionsfor Beam and Girder Molds; and I do hereby declare the following to be afull,-clear, and eXact description of the invention, such as will enableothers skilled in the art to which the drawing.

it appertains to make and use the same.

This invention'relates to new and useful improvements in metalconnections for beam and girder molds and the principal object of theinvention is to provide a device particularly adapted for" use inconnection with poured concrete construction to prevent the liquidconcrete from flowing out of the forms at the joints.

Another object of the invention is to-provide a device which will enablethe forms to be readily wrecked after the concrete has set.

Still another object of the invention is to provide a device which isadjustable in the beam form so that slight variations in the distancesbetween girders may be taken up by the sliding into or out of the beamform this improved connection.

A further object of this invention is to enable the device to be usedwithout providing various lengths of beam forms in connection withcolumns which reduce toward their upper ends as the connection may beadjusted to compensate for the variations of length of space.

With these and other objects in view this invention consists in thenovel combination and arrangemnt of parts which will be fully set forthin the following specification and acompanying drawings, in which Figure1 is a fragmentary perspective view of this improved connectionattached'thereto. Fig. 2 is a longitudinal sectional view through thedevice illustrated in Fig.1.

Fig. 3 is a detail-perspective view of the connection, and Fig. 4illustrates the device in use, in molding beams showing the samecompensating for the varying thicknesses of columns.

Referring to the drawings, the'numeral 1 designates the bottom of theconnection which rests in the bottom 2 of. the beam mold. The sides 3are formed integral with the bottom 1 and extend upwardly therefromlyingagainst the inner faces of'the a beam and girder mold showingSpecification of LettersPatentu Pafentd J 1y 18, 1916 Application filedNovember 17,1915. Serial no. 62,044.

flanges 5 are formed at the upper edges of the side walls 3 and engageon the upper edge of each side wall4 of the beam mold or form to preventthe liquid concrete from flowing down between the walls 3 and 4. Formedat the inner ends of the walls 3 are the outturned wings or flanges 6,the upper edges of which are formed with the flanges 7, which conform tothe flanges 5asclearly shown in adapted to engage the side wall Sjof thegirder form designated generally by the numeral 9 and formed on thebottom1 of the connection is a down-turned flange or wing 10 whichengages the wall of the girder form 9betweentheupper edge of the' recessin which the connections seat and thebottom V 11thereof.-'

The beam form is designated generally by the numeral 12 and it will beseen that the necessity of making a tight fit between the ends of thebeam form and the sides of the girder form is eliminated, as the con-,nection will prevent the material from flow ing out of any crack whichmay be left therein. It is to'be understood that if so suitable nailsmay be' driven wings 6 and 10 of the connecfirmly hold the same againstdesired, through the tion so as to accidental movement process of theconstruction.

As shown in Fig. 4, it will be seen that the column mold is designated.by the numeral 13 and the inner-wall 14 thereof is provided with theopenings for the reception of the connection andv saidconnection isplaced in the opening in the same manner as it is placed in the recessin the girder mold. It

-will be. seen that thebeam mold 12 is supported on suitable cleats 15secured to the outer faces of the girder and'column mold and when theconcrete is set and it is desired to remove the vmold, the cleats 15 areremoved, thus permitting'the' beam forms to during the pouring.

The wings or flanges 6" are drop away from the finished work, thusfacilitating the wrecking of the form. It

will be noted upon reference to Fig. 4 that I the. cleat 15 forsupporting'the beam mold 12 at the upper end of the column is.preferably supported ont a suitable bracket 16 so as to insure theproper" positioning of the beam mold regardless of the amount ofreduction of the thickness of the column.

From the foregoing, it will, be apparent that a particularly simple andeflicient c0nnection is formed which will prevent any loss of theconcrete, due to its flowing through any openings left between thejoints of the mold and also the possibility of the material flowing intothe device between the mold and the connection is eliminated as theflanges 5 and 7 will serve to prevent this.

While in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that such changesmay be made in the com bination and arrangement of parts as will fallwithin the spirit and scope of the appended claims.

What is claimed is:-

1. In a concrete mold, a beam form and a girder form, a metallicconnection comprising a bottom, side walls formed integral therewith,said bottom and side walls being adapted to fit within the beam form andoutturned flanges at the ends of the bottom and side walls adapted tofit the side wall of the girder form to form a tight con nection betweenthe girderand beam form.

2. In a form for concrete construction, a girder form and a beam form, aconnection Copies of this patent may be obtained for five cents each, byaddressing the comprising a bottom, upturned side walls on the bottom,flanges at the upper edges of the side wall, said flanges being turnedoutwardly, the connections being adapted to seat within the girder formso that the flanges at the upper ends of the side walls engage the upperfaces of the side walls of the beam forms, wings at the inner ends ofthe side walls and of the bottom, said Wings being adapted to engage theinner face of one of the side walls of the girder form and outturnedflanges'at the upper edges of the Wings on the side walls, said flangesbeing adapted to overlie the upper faces of the side walls of the girderform to cooperate with the first mentioned outturned flanges inpreventing the concrete poured into the molds from passing between theform and the connection.

In testimony whereof I aflix my signature in presence of two witnesses.
